MEASUREMENT OF THE POROSITY OF MACROPOROUS MATERIALS BY THE GASDYNAMIC METHOD

摘要

We outline a method for measuring the porosity of macroporous materials. The main advantage of this method compared with familiar methods is the significant increase in the number of materials which can be studied. This means industrial use of the method on production lines is feasible. Furthermore, the method can be sued To determine parameters indirectly characterizing a porous structure 9the specific surface area of materials and The adsorption-desorption isotherms).
